Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe production technology, and in particular to a fixture for seamless steel pipe production. Background Technology

[0002] In the field of seamless steel pipe production, fixtures are key components that ensure smooth production and product quality. Currently, existing fixtures for seamless steel pipe production have many shortcomings.

[0003] On the one hand, the clamping range of some fixtures is fixed, making it difficult to adapt to the production needs of seamless steel pipes of different specifications. When producing seamless steel pipes of different diameters or lengths, it is necessary to change to different models of fixtures, which not only increases production costs but also reduces production efficiency and affects the continuity of production.

[0004] On the other hand, some clamps have poor clamping stability. During the production process, seamless steel pipes may shift or wobble due to external forces, leading to reduced processing accuracy or even scrap. Moreover, existing clamps are not structurally sound enough to support and press seamless steel pipes, failing to apply force evenly and easily causing surface damage to the steel pipes, thus affecting product quality.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Identical components are indicated by the same reference numerals.

[0015] This embodiment provides a clamp for the production of seamless steel pipes, which mainly consists of an insertion mechanism 1, a moving mechanism 4, a supporting component 5, and a pressing component 6. The various parts work together to achieve stable clamping of the seamless steel pipe.

[0016] In this embodiment, the insertion mechanism 1 includes a support plate 101, insertion plates 102, and insertion fixing vertical plates 103. First, the support plate 101 is horizontally fixed on top of the mounting frame 2, ensuring that the support plate 101 is securely installed and its levelness meets design requirements. Then, the two insertion plates 102 are horizontally inserted into the side walls of the support plate 101, ensuring a tight fit between the insertion plates 102 and the support plate 101. Finally, the insertion fixing vertical plates 103 are symmetrically installed below the two insertion plates 102. The insertion fixing vertical plates 103 can be fixed by welding or bolting to enhance the stability of the insertion plates 102.

[0017] In this embodiment, the moving mechanism 4 includes a dual-axis drive motor 401, a moving vertical plate 402, a moving threaded rod 403, a lead screw and nut pair 404, and a moving connecting frame 405. First, the dual-axis drive motor 401 is fixedly installed at the center of the lower end face of the mounting base 3, which is then fixed at the center of the lower end face of the insertion mechanism 1. Next, the moving vertical plate 402 is symmetrically arranged below the support plate 101, with the moving vertical plate 402 located on both sides of the mounting base 3 and evenly distributed in a straight line with the mounting base 3. Then, two moving threaded rods 403 with opposite thread directions are fixedly installed on the two output ends of the dual-axis drive motor 401. The end of the moving threaded rod 403 away from the output end of the dual-axis drive motor 401 is rotatably mounted on the inner wall of the moving vertical plate 402 via a bearing, ensuring that the moving threaded rod 403 can rotate smoothly. Next, the lead screw nut assembly 404 is threaded onto the movable threaded rod 403, and the movable connecting frame 405 is fixedly installed between the lead screw nut assembly 404 and the insertion fixed vertical plate 103, so that the movable mechanism 4 and the insertion mechanism 1 are fixedly connected.

[0018] In this embodiment, the support assembly 5 includes a support bushing 501, a support ring plate 502, a fixing bolt 503, and a fixing nut 504. The two support bushings 501 are fixedly installed on the two insertion plates 102, either by welding or by bolting. Then, the support ring plate 502 is inserted into the two insertion plates 102, allowing it to mate with the insertion plates 102. Next, the fixing bolt 503 is inserted into the two support bushings 501, and the fixing nut 504 is threaded onto the fixing bolt 503. By tightening the fixing nut 504, the support ring plate 502 is fixed between the two insertion plates 102, thus supporting the seamless steel pipe.

[0019] In this embodiment, the pressing assembly 6 includes a pressing connecting frame 601, a pressing threaded rod 602, an insertion plate 603, a limiting nut 604, and a pressing ring plate 605. First, the two pressing connecting frames 601 are symmetrically and horizontally installed on the outer wall of the bearing plate 101, ensuring the pressing connecting frames 601 are securely installed. Then, the two pressing threaded rods 602 are respectively fixed on top of the two pressing connecting frames 601. Next, the insertion plate 603 is inserted onto the two pressing threaded rods 602, and then the two limiting nuts 604 are respectively placed at the upper and lower ends of the insertion plate 603 and threadedly connected to the two pressing threaded rods 602. The height of the insertion plate 603 can be adjusted by adjusting the position of the limiting nuts 604. Finally, the pressing ring plate 605 is fixedly installed between the insertion plates 603 for pressing the seamless steel pipe.

[0020] In actual use, the dual-axis drive motor 401 starts, driving the movable threaded rod 403 to rotate. Since the threads of the two movable threaded rods 403 turn in opposite directions, the screw nut pair 404 will drive the insertion fixing vertical plate 103 to move, thereby adjusting the position of the insertion plate 102. The seamless steel pipe is placed on the supporting ring plate 502, and the limit nut 604 is adjusted to make the pressing ring plate 605 descend and press the seamless steel pipe, achieving stable clamping of the seamless steel pipe, which facilitates subsequent production and processing operations.

[0021] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
